Aren't puberty blockers primarily meant to prevent children with gender dysphoria from experiencing the physical disadvantages of going through the puberty of the wrong sex? Obviously a study where children are given the puberty blockers won't be able to measure the impact of all the harmful effects that were prevented (neither physical nor mental health-wise).

The way the article is worded, it almost sounds like they were expecting them to work like mood enhancers. I mean, it's somewhat interesting that there were different outcomes in both studies, but it doesn't speak in any way against the use of puberty blockers.
